The position vofthe .vorkgin the Clan'iping `jaw'vs'fis controlled pfby suitable 'ejector means which, after the-nailingger staplingL oa? thei'rst -lsl-at, parti ally ejects the bei; when the second slat is stapled or nailed. rihis consists of an ejector head 28 having ejecting plungers 281, which pass through guides Q83 carried by the :red aws 15 and 16, being detailed particularly in Fig. 2. The ejector is actuated by a cam 29 carried on a shaft 201 supported at the encs of the brackets 19, 20. The head :is provided with a.projectingmember QSftCOntaining a slot 285 which embraces roller 292 on the shaft Q91.

with cani abutments 286 and 287 which cooperateV with the oblong cam 29 to reciprocate and actuate the ejector.

The camsln t 291 driven from sprocket wheel onthe main shaft 27 which connects by a sprocket chain 277 to sprocket wheel 292% on the said cam shaft 291, the saine being geared in the ratio of one to two so thatthecsnn shaft turned 4half over i each revolution of the main shaft l cam having a suit ble dwell 291C sothat thev work remains stationary during the eperation of the stapling heads.

The ejector heads are urged in by means of. springs `295 which factilitates their operation. y,

The mechanism is driven by anv'suitable gear means y not necessary to or il here as such are in use on machines of this type lo give them the .necessary intermittent movement for the operations required. The machine operates witi great facility as will be seen by a consideration of its movements.

'l he operator places `the box ends 7 and 8 and the mid-parti nl) in the work jaws with `the machinev setin the position as indicated in Fig, il. A pair of slats l() are then put in position 'and the machine is thrown in gear to operate. rEhe crossliead descends carrying the Staplers (i, 6 down andV putting a pair of staples at each end of the partition, stapling the front slats securely in place. Continued evolution of the maj chine throws the cam shaft 291 and operates the cam 29 wiich throws the ejector plungers 281, 282 at each end against the ends 7 and 8, carrying them out so that the rear slat comes into proper position for stapling. The stapling movement is then completed and the continued evolution of the machine withdraws the ejectors to the Cim or initial position indicated in. Fig. 2 and the stapler is raised. No ejector is needed for the centralpartition 9 as it is carried along because vifi/Then the first two slats at one side are stapled, the

. box or crate is turned down on its top and the evolution is repeated which staples the bottom slats in place.

The bof; is then turned down on its sise' and another evolution of thevmachine completes the second side of thebox, thus putting on the two sides The and bottom and leaving the top open. machine thus works with great rapidity.

Trie member 23 is' also providedr` Lacasse Of course, it could be operated without putting in this central partition and the mi.,- chine could be operated for making a very great variety of boxes or crates as a consequence.

1t is especially desirable for and l desire to claim it especially as an orange crate machine and also to claim it broadly as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Lets ters Patent is:

1. In a machine of the class described, the combination of a suitable base, end uprights connected at the top, a reciprocating carrier headin guides on the said uprights, staple drivers carried `by thev said head disposer to drive staples into a boi; tlierebeneath, end supports for receiving the box ends to support them while being stapled, an. intermediate support for the central boi: partition, a fixed shaft betweenv the said upright-s, brackets at each end, a roclrshaft carried by the said brackets, fixed jaws clamped to the said fixed shaft and Vwith extension bearings embracing the roclrshaft, slidable clamping jaws on said shafts to coact with the fixed jaws with springs for-holding them yieldingly in open position, cam arms on the said roclrshaft disposed to act upon the slidable jaws, cam rollers 'on said slidable jaws to coact'with the said cam arms, an ej ector head at each end of the machine with an ejector plunger guided for ejecting and controlling the movement of the said bex ends, oblong cams on a suitable cam shaft carried by the said brackets in parallel relation to the roclrshaft and fixed shaft, a slotted guide projection on each of the said ejector heads and having cam abutments for'cooperating with the said cams, the said cams eaclibeing provided with a dwell to hold the box at rest while it is being clamped and stapled, a drive shaft, a gear on said shaft to drive the cam shaft at one half the rate ofthe drive shaft, eccentrics at each end of the drive shaft with connectionsV for reciprocating the; carrier head, andl an intermediate eccentric on said drive shaft with a connection to said rockshaft timed to actuate the jaws and clamp the work while the same is being stapled.
